In amplifier circuits at very-high, ultra-high, and microwave radio frequencies, a gallium arsenide field-effect transistor (GaAsFET) is a specific kind of field-effect transistor (FET). This covers the range of electromagnetic radiation from about 30 MHz to the infrared band.
The GaAsFET is renowned for its sensitivity and in particular for producing a negligibly small amount of internal noise.
This is due to the remarkable carrier mobility of gallium arsenide. The semiconductor material allows for quick and easy movement of the electrons and holes. A depletion-mode device, the GaAsFET.
This indicates that it conducts when no voltage is supplied to the control electrode (gate), and that the channel conductivity diminishes when a voltage is applied to the gate.
The global gallium arsenide field effect transistor market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Expanding Toshiba’s Ku-Band Power Amplifier Lineup For Microwave Radios are New Higher Power 18W and 30W GaAs FETs. Toshiba America Electronic Components, Inc. and Toshiba Corp.
announced the addition of two higher output power devices with wattages of 18 and 30 to their array of Ku-Band gallium arsenide field effect transistors (GaAs FETs) (W). In TAEC’s stand, the new power amplifier GaAs FETs will be displayed.
The new GaAs FETs, TIM1213-18L and TIM1213-30L, are intended for use in microwave radios for microwave links and satellite communications and operate in the 12.7 to 13.2 GHz range.
Other current Toshiba GaAs FETs in this frequency range have power output ratings of 2W, 4W, 8W, 10W, and 15W.The TIM 1213-18L has a power efficiency of 28%, output power at 1dB gain compression point (P1dB) of 42.5 dBm (typical), power gain at 1dB gain compression point (G1dB), and 6.0 dB (typical).
P1dB is 45.0 dBm (typical), G1dB is 5.5 dB (typical), and power added efficiency is 23% for the TIM 1213 – 30 L.
